Anaerobic digestion (AD) now generates more energy than the landfill gas sector, according to new figures.
The latest figures from the Anaerobic Digestion and Bioresources Association (ADBA) reveals that the UK’s 540 anaerobic digestion plants now generate more energy than landfill gas – and represent 2% of national gas production, the industry association has claimed.
“AD-derived green gas is an important part of the UK’s energy mix as it performs two roles – it makes use of waste and is an environmentally sustainable fuel”
This success can be largely attributed to the growth of the biomethane sector, according to ADBA. With a total of 86 biomethane plants having applied for support under the Renewable Heat Incentive, the biomethane sector currently generates 2.6 TWh of energy, enough to heat 167,000 homes or the whole of Cardiff.
However, ADBA believes that with the right support, biomethane, or “green gas”, can deliver as much as 80 TWh – 30% of household gas demand or sufficient fuel to power 80% of lorries by 2030.
“AD-derived green gas is an important part of the UK’s energy mix as it performs two roles – it makes use of waste and is an environmentally sustainable fuel,” says Reed Landberg, Global Renewable Energy & Environment Team Leader for Bloomberg News, who will chair a panel debate at the ADBA National Conference 2016.
“The fact that AD is also a source of heat makes it more important still, as heat is currently centre stage in terms of UK energy policy.”
ADBA National Conference 2016 on December 8 will also consider whether food retailers could be the saviour of small scale AD; what industry can learn from nature; why England is still lagging behind Scotland, Northern Ireland and Wales in regard to separate food waste collections; and how the biomethane sector will develop between 2017-2021.
The shift is reported in the latest analysis by the Anaerobic Digestion & Bioresources Association (ADBA), which notes that more than 100 plants have come on-stream this year.
ADBA says that 86 biomethane plants have applied for support under the Renewable Heat Incentive and the biomethane sector generates 2.6TWh of energy.
But the association says biomethane could deliver as much as 80TWh with the right support, sufficient for 30% of household gas demand.
